Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.

A Mathematical Perspective on the Influence of Allee Effects in Oncolytic Virotherapy
MathematicsThis article is concerned with the mathematical modeling of cancer virotherapy, emphasizing the impact of Allee effects on tumor cell growth. We propose a modeling framework that describes the complex interaction between tumor cells and oncolytic viruses.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Non-Robust Dynamic Inferences from Macroeconometric Models: Bifurcation Stratification of Confidence Regions [PDF]
Grandmont (1985) found that the parameter space of the most classical dynamic models are stratified into an infinite number of subsets supporting an infinite number of different kinds of dynamics, from monotonic stability at one extreme to chaos at the ...

Spatiotemporal pattern formation in a three-variable CO oxidation reaction model
Condensed Matter Physics, 2018 The spatiotemporal pattern formation is studied in the catalytic carbon monoxide oxidation reaction that takes into account the diffusion processes over the Pt(110) surface, which may contain structurally different areas. These areas are formed during CO-

Direct SMBH Formation Driven by Runaway Stellar Collisions in Globally Unstable Stellar Systems
Astronomische Nachrichten, EarlyView.ABSTRACT The fueling problem addresses the ultimate fate of the reservoirs of gas and stars driven into the deepest gravitational potential wells of galaxies, thus it may contain the Universe's densest concentrations of gas and stars. This raises a key question: does the infalling material collapse directly into a supermassive black hole, or can it ...

Who Cares About Carbon Performance Strategy? Ownership Structure as a Driver for Carbon Performance
Business Strategy and the Environment, EarlyView.ABSTRACT This research aims to highlight the empirical, theoretical, and corporate governance arguments employed in the academic literature that examines ownership structure as a determinant of carbon performance—a key element in contemporary climate governance frameworks.
